External network access authentication system and authentication method based on hardware access card

Abstract

The invention relates to an external network access authentication system and an authentication method based on a hardware access card. The external network access authentication system based on the hardware access card comprises the following steps: an authentication server in connection with the internal network adopts a hardware access card as a peripheral device to connect the external network; the hardware access card is externally connected with a client through the external network, and the hardware access card is internally connected with the CPU through a peripheral bus; the CPU is connected with the internal network through a network card; the client and the hardware access card must pass bidirectional authentication; and the hardware access card is used as a safety boundary forthe connection of the external network and the internal network. The external network access authentication system and the authentication method based on the hardware access card in the invention adopt the hardware access card as the peripheral device to connect the external network; the hardware access card is used as the safety boundary for the connection between the external network and the internal network; the interface is simple and clear so that the server is more strictly separated from the network where the client is located, thereby avoiding the risk of the authentication server being invaded; and the external network access authentication system and the authentication method based on the hardware access card can work in cooperation with other existing servers and have good applicability.

Description

technical field [0001] The invention relates to an external network and an internal network interconnection technology, in particular to an external network access authentication system and authentication method based on a hardware access card, belonging to the technical field of data communication. Background technique [0002] Under the background of the rapid development of network communication technology, network information and various applications are becoming more and more popular. This article is referred to as intranet for short; extranet: Internet, this article is referred to as extranet for short, such as the Internet). The internal network is relatively safe, and will neither be attacked by hackers from the external network nor leak secrets. However, because the external network is full of many unsafe factors, such as: malicious attacks by hackers, virus infection, etc., it always threatens the security of the internal network. Users need to access the intrane...
